This past week I started designing the PCB, read STM32WB55 reference manual, and prepared for the upcoming design presentation.
I started the PCB design using fusion360 on the ANSYS computers. I exported a PCB schematic of STM32WB55 from the internet and read the reference manual about how to drive the SPI peripheral. Because we haven’t get the screen to prototype the circuit, how the microcontroller is connected to the screen (such as which GPIO ports to use) is still contingent. I plan to use diagrams to demonstrate the circuit. For MVP, I reviewed the electrical behavior of diodes and plan to finish the circuit design by tomorrow.
The current progress is on schedule, I think I can get hardware development fully going once receiving the parts.
For next week, I’m delivering the design presentation for my group and I plan to start prototyping the circuit and make progress on both firmware and PCB design. For firmware, I target the goal of a successful programming of the screen using the SPI peripheral on nucleo board.
